Application filed July 23,

T0 aZZ whom it may concern:

Be it known that I, FREDERICK (J. ECKJ'IL MAN, a citizen of United States, residing at New York city, in the county of New York and State of New York, have'invented new and useful Improvements in Lock-Controlled Gut-Offs, of which the following is a specification.

This invention relates to lock controlled cutoffs.

More particularly the invention relates to lock controlled cutoffs to be employed in conjunction with a conduit between a source of fuel supply and a point of consumption of the fuel.

Some of the objects of the present invention are: To produce a lock controlled cutofi for a connection in a conduit which includes a cutoff means for establishing and disestablishing the passage through said conduit and operating means for operating the cutoff means, the operating means being operable by virtue of the operation of the locking means employed, and safety locking means operative to maintain the cutoff means in a condition to disestablish the pas sage through said conduit to prevent the operation of the cutoff means when the oper ating means is destroyed; to employ cutoff means in the fuel supply conduit which is under the influence of separate and distinct locking means,- one locking means being operable for the successful operation of the cutoff means, and the other locking means being operable automatically upon the de-' struction of a part of the means for effecting the operat1on of the'cutoff means.

With these and other objects in view, theinvention resides in the particular provision, combinat1on, relative d1spos1t1on and operation of parts hereinafter fully described and illustrated in the ing, in wh1ch:

The lock controlled cutoff of the present 1nvention has some of the features of the device disclosed in a patentxgranted to me $11,214,441. The specific features of construction of those parts in this device which are used in the device of the patent mentioned may be fully understood as to con struction and operation by the description and illustration of the said patent.

The device of the present invention, generally, comprises a conduit 10, cutoff means 11 connected to said conduit for establishing and 'disestablishing the passage therethrough,

cutoff ooerating means 12, permutation looking means 13, which controls the operation of the cutoff operating means, and safety locking means 1 1- which operates in CD11.

junction with the means 12 to prevent the operation of the cutoff means 11 in the event that portions of the means 12 are cut, broken or otherwise destroyed; Y

The conduit 10 in the present instance is intended to be connected between a source of fuel supply such as gasoline, and the manifold of an engine of an automobile. As stated the cutoff means 11 is arranged in operative connection with the conduit 10 for establishing and disestablishing communication between the fuel supply and said manifold. The said cut-off means 11 com prises a casing 16 made'of plates 17 18 and 19 and parts 20 and 21 between which the part 16 is bolted by locking bolts 22. The plate 18 has an opening 28, opening 24:, opening 25 and opening 26. Because of the fact that the plate 18 is arrangedv between the plates 17 and 19 recesses will be defined by virtue of said openings. A cutoff 27 is pivoted as at 28, and is disposed for movement in the opening 23 to either close or open the aligned holes 29 in the plates 17 and 19 and the parts 20 and 21 which com- Inunicate with the passage of the conduit. A portion of the cutoff 27 has teeth 30.

In order to effect the movement of the cutoff 27 the means 12 hereinbefore mentioned is employed. The means 12 comprises a rack 81 which is disposed in the opening 25 a s rin 32 flexible connection 33 ush button 34-, member 35 and push button 36. The teeth of the rack 31 are in meshing engagement with the teeth 30; the spring 32 is arranged between the end of the rack 31 and the end wall of the opening 25; one end of connection 33 is attached to the rack 31 and the opposite end thereof is conneeted'to a part 8?. The part ili'is under the influence of a spring 38 surrounding the reduced part 3i) ot' the button 3% and has a portion t0 extending in a bore in the part 39 and is held against sepa'ation but is allowed to have relative movement with respectto the part 39 by virtue of a pin and slot connection tl. The part Si is bifurcated as at tor a purpose to appear. The

push buttons 3st and 38 and the member are arranged in a casing; #53. Theinember is arranged for movement and is disposed between he pusii buttons 8t and 36. The said memberhas tongue "at and oblique kerf s5 and a nose The member 35 has slidablemovement and this is causedby virtue of a pin l7 disposed in the liert 4-5; the said pin being carried by the turcations 48 of said button 36. The push button 36 is acted uponby a spring i9. When the holes 29xare obstructed by the cutott 2? the push'button S iwrll be down or in and held in such position by virtue ot the {JO-EXCUSE of the nose lt) with the spring presset latch carried by the button 3%. At this ;time the sarine' aressed do 51 has a vorton -34 is allowed to more upwardly. the spring 58 ofthepart 5'? will cause said part a 57 to move upwardly with the result that :the-dog olwill be-putin neutral position which action wi'hbe toll wed in inediately b the movement of the rack 31 dueto the ii'urther niovement of the push but-ton Set by *virtue otthe action of the spring while the spring 38 serves to hold '37 seated against a stationary disk 38, and rte-take up lost motion between the push buttl e feet of the part ten 3%; part. 37 and part. 57 positively and evenly thus causing the cutoli' to move positively and-evenly to aposition in which the holes'29 i lll be unobstructed. Thepressure of the: spring .88 is :greater than .thespr ng 132 ,withthe resultthat said spring 38 not only prevents lost motion between the parts -mentiened but upon pressure of the button 3% the spri-ng 38 also acts tOliQQP the valve portion otthe out in closed position.

to an inoperative position the tension or" the spring 38 isalso released.

Inorder that the push button 36 may be pushedinwardly to elfect the movement of the member 35 it is necessary to operate the locking "means 13 which is substantially similar in construction and operation of the loc ting means disclosed in the aforesaid patent, whereupon the tongue id will be allowed to enter aligned recesses 59 in parts of the means'l3. 'lVhen the recesses 59 are aligned the member 35 may be reciprocated by operating push button either to permit the push button to move outwardly or to permit the same to be pushed inwardly.

The fiez-zible connections ant 35 are encased byv a. tubing 60 to prevent unauthorized i'nanipu .tion 'iththe parts of the device. To further protect against the treepassers, means Il ibetorementioned is provided and consists of a flexibleconnection 1 connected to a ball 62 under the influence of a spring 63; the opposite end otthe connection (31 being attached to a portion ol the bushing 64:; and the ball and spring disposed in the opening 26, one wall of which is inclined so that when connection 61 is cut the ball will be forced into the small end oi the opening 25 to move against the rack ill to hold the latter against movement andthe cutoli 27 in closing position. Extra connections such as the ones 33, 55 and 61 may be employed to foil trespassers. The connections mentioned are preferably of piano spring steel wire. The tubing 60 extends troin within theportion of the casing 16 to within a portion of the bushing :64. which latter is held in place in a portion otthe casingd?) byscrews or the like.

From the toregoingit will be'manitest that by manipulating permutation means in a proper manner the recesses 59 may, be brought into alignn'ient whereupon the push button 36 may be pushed inwardly and the push button Sat and connected parts will be operated automatically to allow the cutoff tomove automatically to anopen position; the push button 36 moving to anormal position when pressure thereon isreleased; that by pressing inwardly on the button 3% the cut-oil 27 may .bemoved to a closing position and in the event that either of the connections and 61 are cut or .broken it willbeimpossible to movethe outed-27 out of its, closingposition.
